Description
Technical Field
The utility model relates to a negative pressure source device and contain its adjustable negative pressure drainage ware convenient to operation.
Background
Various devices have been used to assist in the drainage of fluids from wounds, particularly wounds resulting from surgery or accident. When in use, the adjustable negative pressure regulator is connected with a drainage tube on the patient body and is used for sucking liquid (such as accumulated water and the like) in the patient body into the drainage device. The vacuum source of the adjustable negative pressure regulator provides a portable source of negative pressure and provides a reservoir for aspirated wound waste.
One of the negative pressure sources of the prior art adjustable negative pressure regulators employs bellows-type containers that reduce their volume against the pressure of an internal spring or by utilizing the deforming force of the container material to provide a vacuum source. This type of construction presents several major limitations, one of which is that, to achieve the required vacuum, the container must have high elasticity to obtain a vacuum of the order of a few tens of kilopascals. This is somewhat impractical in terms of cost for efficient production and only produces a small vacuum, which will dissipate quickly when the liquid is injected.
Another type of device for aspirating and collecting wound fluid uses a disposable reservoir connected to a reusable, electrically powered pump, requiring sophisticated and expensive electronics, pumps, and rechargeable batteries or power sources. The inherent complexity of such devices requires a significant additional expenditure for initial procurement and maintenance of the pump and control equipment. Although the fluid container is disposable, it is necessary to provide special provisions for non-disposable components such as the pump assembly to prevent contamination from the discharged wound fluid.
There is also a wound fluid collector which uses a pre-evacuated container. However, the switch of the collector is a rubber tube structure with a tube clamping plate, the structure has general tightness, and the opening and closing of the negative pressure source are very laborious.
The latter form of wound fluid collector is still another form which employs a regulating valve with a push rod to open and close the negative pressure source. This does contribute to the opening and closing action of the negative pressure source, but still has some other inevitable disadvantages during transport, the push rod being free of leak-proof mechanisms during transport, the push rod possibly sliding due to transport, causing the negative pressure source to be opened.
